Central air conditioning is no longer just"Blowing cold air" is not that simple—it concerns the entire office building's energy consumption, ceiling height, and even employee productivity. Suzhou, as a highland where the manufacturing and service industries in the Yangtze River Delta converge, experiences both humid rainy seasons and cold winters, demanding more refined and "local" requirements for air conditioning comfort, stability, and maintenance.

When faced with a plethora of brands and models, how do you choose the right one without taking many detours? Prioritize the four-step filtering process: "area → system → brand → budget."

 Firstly, lock the system format based on office space.

Office Space < 1,000 Sq. M.: Multi-split (VRV/VRF) Systems – Quick Installation, Flexible Zoning

Office Size: 1,000-2,000 sqm - Multi-split or Air-cooled Heat Pump Modules - Consider Floor Load Capacity and Unit Position

Office Space: 2,000-5,000 Sqm - Air-Cooled Screw/Modular + Fan Coils – Moderate Initial Investment, Enhanced Energy Efficiency

Office Space > 5,000 sq. m: Centrifugal Chilled Water Unit + Air Conditioning Unit - High Cooling Capacity, High Energy Efficiency Ratio
